need waaaay more info if you want ppl to be able to help you out. Firstly by bolt on i guess you mean standard ex manifold/ standard position? what injectors/fuel pump/computer do you have? waht is your budget? most importantly what power figure do you want?

have a really good read of the rb25 dyno results page

http://www.skylinesaustralia.com/forums/Rb...yno-t55845.html

and then google parts stores for each of the items ppl list in their mods if you want to work out how much each power figure might cost you...

(the short answer, in my opinion, is a 3076R) but read the forums, its all there and its all been done a lot of times before..

discussion of 35r and t04z (rly big option for an rb25)

http://www.skylinesaustralia.com/forums/Gt...is-t246293.html

discussion of where to spend money on an rb25 might be of use to you

"280-320rwkw seems to be GT3076

250-280rwkw seems to be GT3071

Thats in the Garretts.

There are the cheaper bush bearing items from Hypergear - you'll have to read the 10+ page thread on those though, im not 100% what is what.

Then you have GCG hi-flows, 260rwkw using the R34 GT-t turbo/OP6 rear housing.

So decide what you want, work it out from what is above, and go search"

Thread on choosing between turbos for r33

http://www.skylinesaustralia.com/forums/R3...tml&hl=3076

and last but not least a thread in the DIY section of bolting up a gt3076 to an rb25..including prices..

http://www.skylinesaustralia.com/forums/Ga...25-t255288.html

etc...

read three times as much as you post. itll save you time and money.

happy reading.

yea thats alot of help

pretty much as above, but it comes down to what your budget is. are you planning on going (sort of) all out and spending 4 or 5k on the project to do it properly (bigger afm and injectors, ecu, etc), or do you simply just want to bolt the turbo on and do it for as cheap as possible? also what power are you chasing?

    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
    • Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
